Usually we need to add log in the project to print some information, if in the project random view log information, or want to print only log of the different levels of log information, as well as the project release, the need to clear the log information, so that the workload is particularly large, So we typically build a tool class that prints log information:public class LogCat {private static final int log_level = 5;private static final Boolean open_log=false;public static void I (string tag

"// println ("TheBank has \ (bank.coinsinbank) Coins"//Player has now left the game. This indicates that you want to set the optional Playerone variable to nil, which means "there is no player instance." When this happens, the Playerone variable's reference to the player instance is broken. There is no other property or variable that references the player instance, so it is freed in order to empty the memory it occupies. Before this occurs, its destructor is automatically called and its coins a

In this case, to encode the conversion, you need to first convert it to Unicode encoding using the Decode method, and then use the Encode method to convert it to another encoding. Typically, you create a code file by using the system default encoding when you do not specify a specific encoding method.If the string is defined like this: S=u ' Chinese 'The encoding of the strin
